Introduction #
The Parallax WiFi module adds wireless programming functionality to Parallax Propeller Microcontrollers
This tip concerns the Propeller FLiP module, and how to connect the FLiP and WiFi modules together.
Connections #
There are 5 connections including power and ground:
| Parallax Propeller FLiP Module | Parallax WX SIP WiFi module |
| P31 | DO (optionally use BAT43 or BAT48 diode, anode to FLiP pin, cathode to WiFi pin) |
| P30 | DI |
| RESn | CTS |
| 3.3V OUT | VIN |
| GND | GND |
If you want to use both USB and WiFi programming at the same time, then install the diode mentioned in the table, between P31 and DO.
If you are powering your FLiP module using a USB Powerbank, Wall Wart, or directly at the VIN pins, then the diode is not necessary (but could still be installed).
WiFi module configuration #
The first time you use the WiFi module you will typically want to visit the built-in settings page using a web browser. Often this is simplest from a laptop; open your laptop WiFi search menu and connect to the Parallax WX WiFi module. That name of the WiFi module will be in this format: WX-123456.
Once connected, open a web browser on your laptop, and visit 192.168.4.1
You will see the WiFi module web screen. Click on the left-side "Settings" menu, and ensure the reset pin is set to CTS. If not, then select CTS from the dropdown, then click "Save to Flash" at the bottom.
Now visit the Networks menu, and follow the instructions to search for, and connect to , your local WiFi network. You will be prompted for a password if required.
Once connected, you can close the browser and your laptop.
Tip: To avoid manually entering your WiFi credentials and WiFi settings, use the technique shown in the video linked below!
Programming #
Once you have the WiFi module configured, it should be visible on your local network. Power on your FLiP module, either using the FLiP VIN pin or via the FLiP USB socket. Then with your favourite Propeller code tool use the wireless programming and serial terminal functions! Many code tools include a hotkey F7 to show a list of available WiFi modules.
Tip: If you don't see your module listed, it might be that your local network has "client isolation" enabled. Consult your router user guide on how to disable that feature.
The connections between WiFi module and FLiP module are shown in the PDF wiring diagram download below.
